> A trans person walks into a store and people just start annoying them?

You have to pay for what you want at the store. That involves a person. That person then tells that they're praying for you to be someone you aren't and never will be.

Do you somehow not encounter people in your everyday life?

Perhaps a better answer than "f off" or "mind your own business" would be "thank you, I'm sure we'll both be blessed by your prayers" even if you don't particularly believe it to be true. It's an answer that will eventually break down barriers over a few years rather than reinforce stereotypes.

As for being oppressive -- it's far better for people who disapprove of you to be saying "I'm going to pray for you" rather than have them say "I'm going to run you out of town at gunpoint and set fire to your house". The latter is the default response for most cultures and most religions across most of the planet.

> just tell people no thanks, f off, or mind your own business.

Sounds like a good way to escalate an already uncomfortable situation. It's damned if you do, damned if you don't.

I offered three entirely different options. "No thank you" to politely decline the offer. "F off" to show your extreme displeasure. And "mind your own business" for public shaming.

Holy crap do people project much.
